SINGLE-TRIGGER DOUBLE-BARREL SPORTING-GUN.-

To all whom it may concern:

Be it known that I, ROBERT JULIUS PETER- SEN, subject of the King of Great Britain, residing at Lench street, Birmingham, in the county of Warwick, England, manufacturer, have invented a new and useful Improvement in Single-Trigger Double-Barrel Sporting-Guns; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention comprises improvements in single trigger double barrel sporting guns and refers to that class of such in which the trigger carries a pivoted member or catch which moves from side to side to engage and actuate the sears alternately, and to that class of such guns which have sliding members on either side of the trigger which are operated by the fall of the hammer to push over the said catch to the other position ready to fire the next barrel; the object of my said invention being to provide improved and simpler mechanism for the specified purpose.

According to my invention I employ a pivoted catch on the rear end of the trigger, in combination with sliding bolts mounted at each side of said trigger arranged to push over said catch to its other extreme position on the fall of the hammer, said catch having a V projection on its forward side against which abuts a roller carried by a sliding plunger. The plunger is slidably carried in the trigger, being pressed outwardly against the catch by a spiral spring which also serves to return the trigger to its normal position after being raised. The side bolts are mounted in an improved manner as also is the sliding member for preventing involuntary firing.

Referring to the drawings. Figure l. is a side elevation of a gun action fitted with my improved mechanism, one side plate and part of the mechanism being removed to more clearly disclose same. Fig. 2. is a plan of same with the hammers and part of the other mechanism removed. Fig. 3. is a longitudinal section through the trigger in its normal position while Fig. 4:. is a similar section with the trigger in its raised or firing position while the sliding member has passed beneath the rear end of the trigger for preventing involuntary firing. Fig. 5. illustrates one side bolt removed. Fig. 6. shows a bracket for supporting the side bolts, in front and side elevations. Fig. 7. illus- Specification of Letters Patent.

trates the upper surface and rear face of the pivoted catch removed.

In the accompanying drawings my invention is illustrated as being applied to an ordinary gun action, the hammer 1 being actuated through any well known mechanism when the sear 2 is raised.

On the rear end of the trigger 3 is a swinging catch l mounted on a vertical shaft, on the lower end of which is a lever 5, one arm of the catch being adapted to pass below the right hand sear to fire the right hand barrel, the other arm to pass beneath the left hand sear to fire the left barrel, Fig. 2 showing the catch in position for striking the right hand scar and firing the right hand barrel. The hand lever 5 enables the catch to be set for firing either of the barrels at will, but in combination with the catch I employ means for automatically shifting the catch over ready to fire the second barrel immediately the first barrel has been fired.

Immediately in front of each end of the catch is a sliding bolt 6, while on the hammer mechanism is a projecting arm 7 which strikes the front end of the bolt 6 when the hammer falls and causes said bolt to move rearwardly and shift the catch to the position necessary for firing the second barrel. These side bolts 6 are slidably carried in brackets 8 having screwed shanks l0 and grooves 11 whereby they may be fixed in position by a screw driver. Said bolts are held in their normal positions by springs 9 acting between one of said brackets and an abutment 12 formed on said bolts.

To prevent the catch remaining in an in: termediate position I employ a spring actuated sliding plunger 18 having on its rear end a roller 14: which engages a V or equivalent projection on the front of the catch and forces said catch into one or other of its extreme and operative positions, and obviously said plunger also prevents the catch being accidentally shifted over, the plunger requiring substantial pressure to overcome the resistance of the spring. Said sliding plunger is slidably mounted in the trigger 3 a spring 15 being compressed between a fixed part of the gun action and the plunger, and performing the two functions of press ing the plunger against the catch and also of returning the trigger to its normal position after firing.

A sliding member 16 is located at the rear of the trigger and has a heel piece 17 When the gun is fired and the trigger raised the shock from the recoil of the gun causes the said sliding member to be propelled forwardly the heel 17 passingbeneath the rear end of the trigger and preventing same falling into its normal position ready for firing. The sliding member is retracted by the spring 18 located in a slot and is slidably held in place by the screw 19 operating in the same slot.

What I claim as my invention is 1. In a single trigger double barrel sporting gun, the combination of a pivoted trigger, a sear on each side of the gun, cartridge striking mechanism, means for actuating the cartridge striking mechanism when a sear is raised, a pivoted catch on the rear of said trigger having an arm projecting beneath each of said sears, a sliding bolt on each side of the gun, and in front of the arms of said catch, means for causing said bolts to push over the catch to its opposite position on the fall of the striking mechanism, a spring around each of said bolts for returning them to their normal positions, a sliding plunger in said trigger engaging the catch for retaining it in one of its extreme positions, and a spring located between a fixed part of the gun action and the plunger performing the two functions of pressing the plunger against the catch and also of returning the trigger to its normal position; all for the purpose specified and substantially as set forth.

2. In a single trigger double barrel sporting gun, the combination of a pivoted trigger, a sear on each side of the gun, cartridge striking mechanism, means for actuating the cartridge striking mechanism when a sear is raised, a pivoted catch on the rear of said trigger having an arm projecting beneath each of said sears, a hand lever on the lower end of said catch for enabling the gun to be set to fire right-left or left right at will, a V shaped projection on the front of said catch, a sliding bolt on each side of the gun and in front of the arms of said catch, means for causing said bolts to push over the catch on the fall of the striking mechanism, brackets for supporting said sliding bolts, screwed stems on said brackets whereby they are fixed, an abutment on said side bolts, a spiral spring around each of said bolts for returning them to their normal positions, a sliding plunger located in said trigger engaging the catch for retaining it in one of its extreme positions, a roller on the end of said plunger for enabling the catch to be moved relatively to the plunger, a spring located between a fixed part of the gun action and the plunger performing the two functions of pressing the plunger against the catch and also of retaining the trigger in its normal position, a sliding member at the rear of said trigger and adapted to pass beneath same when the jaw is fixed, and a spiral spring for returning the said sliding member to its normal position; all for the purpose specified and substantially as set forth.
